Noumenon

I've played other titles where Taunt would give you 30% damage on the target until the target hit you 3 times. So for the sake of ballancing defence and ressist it could be that Gauntlet gives you X% extra damge on taunted target as long as you have Y% or more HP.

I think the issue really is that the Brute passive is overperforming.

The issue is pretty much gone when you get the aggro auras. I also belive the aggro system is progressive, so the more stacks of taunt you got on the target the less it takes from friendly players to pull the aggro from you, this is how most older MMO aggro system worked atleast. This means that the fault is really due to your team members not giving you enough time to build up aggro.

For the sake of archetype viability and balance I would like to suggest a feature that gives more value to bring a power set combination that isn't so focused on AoE damage. Especially in large groups where classes like Stalkers aren't really a thing. The idea would be to have the server calculate how much of the percentage of the HP on the NPC that was lost by doing ST based attacks, as well as how much was lost doing AoE based attacks and then add something like a 20% bonus to the amount of that was done by using ST based skills. Example: Killing a NPC that would normally give you a total of 100 xp and 100 influence. With my suggestion it would function like this: ST based attacks that does 64% of the damage and AoE based skills does 36%. 36 xp and influence from AoE attacks and 77 xp and influence from ST damage for a total of 113 xp and influence.
